Ok, I want the process on how you are doing #4, from starting at #3:
3. I go to the forum and read the posts
4. I find a post that I dont like, but want to read it or check the posting IP so I unapprove the pst
What are you clicking, what buttons, what do they say... Tell me every little step... because editing a post and choosing "unapprove" is not doing for us, what you say it's doing for you...
